Plastic is everywhere, from food packaging to textiles
Plastic is a relatively new invention, with the first examples dating back to the late 1800s. However, it has become one of the most widely used materials in modern times due to its versatility and low production cost. Plastic is so pervasive that it is everywhere, from food packaging to textiles, healthcare, construction materials, and furniture.
The average annual plastic consumption in Western Europe is about 150kg per person, more than twice the global average of 60kg. Global plastic consumption is accelerating, with over half of the plastic ever manufactured produced since 2000. The production of plastic contributes to climate change, with annual emissions in the EU amounting to 13.4 million tonnes of CO2.
The packaging sector is the largest generator of single-use plastic waste in the world, with approximately 36% of all plastics produced used in packaging. This includes single-use plastic food and beverage containers, 85% of which end up in landfills or as mismanaged waste. Plastic food containers and packaging are so common that they are difficult to avoid entirely. However, individuals can make a difference by shifting their behaviour to avoid single-use plastic products whenever possible and reusing or repurposing plastic items until they can no longer be used.
Another significant source of plastic pollution is the fashion industry, with about 60% of the material made into clothing being plastic, including polyester, acrylic, and nylon. Laundry alone causes around 500,000 tonnes of plastic microfibres to be released into the ocean each year. Microplastics from synthetic textiles account for 8% of European microplastics released into the oceans and 16-35% globally.

Plastic pollution is a human and planetary health crisis
Plastic pollution is a pressing issue that poses a significant threat to both human and planetary health. It is a crisis that spans across biological layers, from the environment to human well-being and rights. At each stage of its lifecycle, from extraction to disposal, plastic has detrimental effects on the planet and its inhabitants.
The production and use of plastic have skyrocketed since the 1950s due to its inexpensive, durable, and lightweight nature. As a result, plastic pollution is now found everywhere, from coastlines to the deep sea, soils, and even in our food systems. The impact of this pollution is far-reaching, with approximately 19-23 million tonnes of plastic waste leaking into aquatic ecosystems every year, altering habitats and reducing ecosystems' ability to adapt to climate change. This directly affects the livelihoods of millions, particularly those in developing nations who rely on marine environments for their diet and economic activities.
The climate-induced downturn of agriculture and fishery industries is exacerbated by plastic pollution, which further compounds the challenges of poverty and unemployment in specific communities. For instance, the Smokey Mountain dumpsite in the Philippines housed 30,000 homeless families for four decades, exposing them to the detrimental effects of plastic waste. Moreover, microplastics generated from plastic packaging and pollution in soils threaten food security and human health, with studies showing links to developmental issues in the neuroendocrine system.
The plastic pollution crisis demands a systemic transformation towards a circular economy, and while there is an increasing trend of policy implementation to combat plastic waste, the COVID-19 pandemic has hindered progress. A planetary boundaries approach has been proposed to define the limits of waste production to ensure the Earth remains habitable for humanity. This crisis requires urgent attention and coordinated global efforts to address the impacts of plastic pollution on both human and planetary health.

Plastic pollution is largely irreversible
Plastic pollution is a pressing environmental issue that poses significant risks to human and ecological health. The rapid increase in plastic production, particularly single-use plastics, has overwhelmed global waste management systems, leading to widespread plastic pollution. This pollution is largely irreversible due to its pervasive and diffuse nature, making effective cleanup extremely challenging.
Plastic waste is found in various environments, including oceans, rivers, lakes, the Arctic, deep seabed, and even in the atmosphere. Once in the ocean, plastic waste is challenging to retrieve. While mechanical systems can collect large pieces of plastic from inland waters, microplastics that form as plastics break down in the ocean are virtually impossible to recover. These microplastics can be carried by ocean currents, spreading plastic pollution globally.
The impact of plastic pollution extends beyond its physical presence. Plastics contain additives and toxic chemicals that can leach into the environment, contaminating air, food, and water sources. These chemicals have been linked to adverse health effects in humans and wildlife, including liver and cell damage, reproductive issues, and even cancer. The ingestion of plastic by wildlife can lead to starvation, intestinal blockages, and death.
Additionally, plastic pollution contributes to ecosystem degradation and alters habitats and natural processes. It affects the ability of ecosystems to adapt to climate change, directly impacting the livelihoods and food production capabilities of millions of people. The problem is further exacerbated by the limitations of recycling. Most plastic is not designed for recycling, and the process often generates hazardous waste and toxic air pollution, underscoring the urgency of addressing plastic pollution at its source.
To address the issue of plastic pollution, systemic transformation is necessary. While mechanical systems can help remove large pieces of plastic from inland waters, the focus should be on preventing plastic waste from entering natural environments in the first place. This involves reducing plastic consumption, improving waste management practices, and transitioning to a circular economy that minimizes the use of non-recyclable plastics and promotes sustainable alternatives.

Plastic is made from toxic chemicals and non-renewable materials
Plastic is everywhere, from the clothes we wear to the food we eat. It has become a household staple for families and communities worldwide. However, the ubiquitous presence of plastic is a cause for concern due to its toxic chemical composition and non-renewable source materials.
The manufacture of plastics typically starts with small molecules called "monomers," which are assembled into long strands known as "polymers." These polymers are derived from fossil fuels, particularly natural gas, and sometimes crude oil. The use of fossil fuels as the primary source material for plastics contributes to environmental concerns as it is non-renewable. Additionally, the extraction and processing of fossil fuels can lead to environmental degradation and greenhouse gas emissions.
The concern regarding plastics lies not only in their source materials but also in the toxic chemicals they contain. Additives are often incorporated into plastics during the manufacturing process to enhance their flexibility, durability, and transparency. These additives, such as bisphenol A, phthalates, and vinyl chloride, are of particular concern due to their potential health risks. For instance, research has linked exposure to these chemicals to hormonal imbalances, reproductive issues like infertility, and even cancer. The issue is exacerbated by the fact that these toxic chemicals can migrate or be released from plastics, contaminating our air, water, soil, and food.
Furthermore, the presence of microplastics in the environment is a growing problem. Microplastics are tiny plastic particles, measuring less than 5 millimeters in length, that are formed through the breakdown of larger plastics due to wear and tear, washing, sun exposure, and heat. These microscopic fragments are easily ingested by wildlife and can accumulate in their bodies, leading to serious health issues and even death. Microplastics have also been detected in human placentas, indicating potential risks to fetal development and subsequent generations.
To address the issues posed by plastics, urgent action is required. This includes phasing out the most toxic and problematic plastic products, eliminating chemicals of concern, and increasing transparency in disclosing the chemicals used in plastic production. Additionally, there is a need to invest in developing safer and more sustainable chemicals and materials, as well as promoting non-toxic reuse and refill systems. While recycling is often touted as a solution, it is important to recognize that most plastic is not designed to be recycled, and the process itself does not address the toxic chemicals and non-renewable source materials inherent in plastics.

Plastic production contributes to climate change
Landfills, where a significant portion of single-use plastics end up, account for more than 15% of methane emissions. The incineration of plastics, another common disposal method, also contributes significantly to carbon dioxide emissions. These emissions, along with those from the refinement and incineration of plastics, represent direct contributions to climate change.
Plastics also contribute to climate change through their impact on the ocean's ability to sequester carbon dioxide. The Ocean University of China found that microplastics impede the growth of microalgae and their photosynthesis efficiency. As plankton plays a crucial role in removing carbon dioxide from the atmosphere, the proliferation of microplastics could diminish their capacity to do so.
The pervasive nature of plastic pollution underscores the urgency of addressing this issue. Plastic waste is estimated to take between 450 to 1,000 years to decompose, with some arguing that it may never fully break down. The accumulation of plastic waste, coupled with the release of harmful compounds during the production and use of plastics, poses risks to human health, environmental well-being, and the functioning of the Earth's systems.
To mitigate the impact of plastic production on climate change, it is essential to reduce the use of single-use plastics and transition towards sustainable alternatives. Banning toxic and problematic forms of plastics, increasing transparency in the chemicals used during production, and investing in the development of safer materials are crucial steps. Additionally, supporting legislation that reduces plastic consumption and purchasing from companies committed to minimizing plastic use can collectively contribute to a significant reduction in plastic waste.

Frequently asked questions
Plastic pollution is a human and planetary health crisis. It releases harmful compounds into our air, food, water, and the environment during production, everyday use, and disposal. Plastic pollution is also largely irreversible. It is too widespread and diffuse to realistically clean up, and it is not possible to remove such contaminants from the blood and tissues of billions of organisms.
Microplastics enter our bodies through the food and water we consume, as well as the air we breathe. A study found that, on average, 60% of fish from 198 species captured across 24 countries contain tiny plastic particles in their organs. Multiple studies have also found microplastics in various types of table salt.
The NRDC's health experts have advocated for phasing out the most toxic and problematic plastic products, eliminating chemicals of concern, blocking the expansion of "chemical recycling," and mandating that manufacturers disclose the chemicals in their plastic products. Consumers can also play a critical role in reducing plastic pollution by properly disposing of their plastic waste and reducing their use of single-use plastics.
